She is renamed "Sahn" in later episodes of Year 2. The name first appears in the script of Journey To Where, but she first appears with the name in Catacombs Of The Moon onwards. The name Sahn also appears on her ID badge, with no surname, although occasionally she still has the name "S Benes" on her ID (in Seed Of Destruction and some scenes in The Beta Cloud).
